Freshman Physics Final Exam

friction

Answer explanation

The force that acts to resist the relative motion of objects or materials that are in contact.

inertia

Answer explanation

The property of any body to resist changes in its state of motion. Mass is the measure of inertia.

Newton's first law

Answer explanation

See of law of inertia.

law of inertia

Answer explanation

Every body continue is its state of rest,or of motion in a strait line at constant speed, unless acted upon by a nonzero force. Also known as Newton`s first law.

kilograms

Answer explanation

The fundamental SI unit of mass. One kilogram is the amount of mass is one liter of water at 4 degrees C.See Appendix A.

mass

Answer explanation

A measure of an object`s inertia ;also a measure of the amount of matter in an object.Depends only on the amount of and kind of particles that compose an object not on it`s location.

weight

Answer explanation

The force on a body due to the gravitational attraction of another body.

newton

Answer explanation

SI unit of force. One newton is the force applied to one-kilogram mass that will produce an acceleration of one meter per second per second.

inversely

Answer explanation

When two values change directions, so that if one increases the other decrease.

Newton's second law

Answer explanation

The acceleration produced by a net on a body is directly proportional to the magnitude of the net force,and is inversely proportional to the mass of the body.
